Hi, There is so much difference in this two products.
1) Totally different design style. Every block here it’s a powerful component with a bunch of different layouts and parameters.
2) Different logic. It’s a plugin, so now you can use Qards with your lovely WP theme.
3) Qards it’s not all about components amount, it’s about consideration of each component. Here you can see only necessary components that every day we can see in the Internet. In the near future, the difference between the two products would be more evident.

When you say it is a plugin, it must be installed with any other theme?
How does it adapt to the theme style?
That is something I don’t really understand… is there any blog post that explains it clearly?
Thanks.

Hi, yes you can use it with any theme. Here https://designmodo.com/qards/first-steps/ we have a few video tutorials. So, you can create design using Qards in the any theme you want (Please check example with WooCommerce).
